用于lte的进一步增强的基于非ca的icic的小区识别的方法和装置

Method and apparatus for cell identification for further enhanced non-CA based ICIC for LTE

Abstract

公开了用于通过为用户设备(UE)选择最适当的小区来支持瞬时业务负载情况的方法和装置,其中选择最适当的小区通过将UE连接到具有减小的发射功率的小区使得UE可连接到较弱的小区。小区间干扰协调(ICIC)是多小区无线资源管理(RRM)功能,其具有管理无线资源使得小区间干扰被保持在控制之下的任务。测量周期性地进行以评估业务负载情况。通过考虑关于资源使用状况和业务负载情况的信息来重新分配资源。具有高业务负载的较强小区的发射功率被减小且资源被重新分配使得UE可接收数据或对较弱的小区执行测量。本发明的某些实施方式在干扰信号存在时处理不同的测量/报告。
A method and apparatus is disclosed to support an instantaneous traffic load situation by selecting the most appropriate cell for user equipment (UE) by means of connecting UE to a cell that has a reduced transmitting power so the UE can connect to a weaker cell. Inter-cell interference coordination (ICIC) is a multi-cell Radio Resource Management (RRM) function that has the task of managing radio resources such that inter-cell interference is kept under control. A measurement is periodically taken to evaluate the traffic load situation. The resources are reallocated by taking into account information about the resource usage status and traffic load situation. The transmitted power of a stronger cell with a high traffic load is reduced and resources reallocated so UE can receive data or perform measurement on a weaker cell. Certain embodiments of the invention deal with different measurement/reporting in the presence of interferers.
